Our Biogas Kitchen
In Germany it was our common practice to compost all of our kitchen waste. Now that we have built an ARTI India style biogas digestor on the porch, however, we only compost the tissue paper, napkins, cardboard, tea-bags and fibrous, cellulosic material that our household generates as garbage. All the food waste (including flower petals and banana peels) go into the blender with warm water and then into the biogas digestor. What we get out is liquid fertilizer for our rooftop herb, berry and vegetable garden, and biogas. We are still experimenting with the yields of gas, but are so far averaging 10 minutes a day for the small size of our digestor and the small quantities of food waste our family of 2 (with a baby) generates. Two days worth of kitchen waste gives us enough gas to usefully cook for 20 or 30 minutes.

Superb video T.H.! Great to see it working for you. I rue the fact that we’re in rented accommodation at the moment – I don’t think our landlord would appreciate us doing this!
Lovely to hear your little man chiming in too!

He suggests that it may be possible to do biphasic digestion, starting with an aerobic process for 24 hours (not long enough to remove all the high energy value) and then giving it to the anaerobes. i haven’t tried this yet. Cows, of course, do it, but they have 4 guts and specialized organisms to break down the cellulose. It is worth experimenting with!

Hi InsAne, thanks for the kind comment — I like your theory about our son (who my wife was holding as she took the video) doing simultaneous translation for the “baby geniuses” out there (did you ever see that movie with John Travolta and Kirstie Alley?).
As for garden waste, the inventor, Dr. Karve from ARTI India told me that high cellulose material like leaves and grass and stalks can’t be digested by the methanogens.

Great videos I like it a lot. Does it work with garden waste like leaves, as well?
